What is the P0561 fault code? What does it all mean?
The battery supplies power for the powertrain control module, (PCM), even when the ignition switch turns off. The PCM keeps a history of fault codes and fuel trim values in its memory. If the voltage drops below a specific level, the PCM considers that there is a fault in either the circuit or the battery. The code P0561 is set by the PCM when the engine is turned on.
The P0561 fault code can affect vehicles of all makes and models, including but not limited to Kia, Isuzu (Chrysler), Opel, Opel, Vauxhall Mercedes-Benz, Subaru Duramax, Duramax, Jeep, Opel, Opel, Opel, Opel, Opel, Vauxhall and Mercedes-Benz.
